Intrepid::Basis_HDIV_TET_In_FEM< Scalar, ArrayScalar > Class Template Reference

Implementation of the default H(div)-compatible Raviart-Thomas basis of arbitrary degree on Tetrahedron cell. The lowest order instance starts with n. Implements the nodal basis of degree n the reference Tetrahedron cell. The basis has cardinality n(n+1)(n+3)/2 and spans an INCOMPLETE polynomial space of degree n. Basis functions are dual to a unisolvent set of degrees-of-freedom (DoF) defined and enumerated as follows: More...

Detailed Description

template<class Scalar, class ArrayScalar>
class Intrepid::Basis_HDIV_TET_In_FEM< Scalar, ArrayScalar >

Implementation of the default H(div)-compatible Raviart-Thomas basis of arbitrary degree on Tetrahedron cell. The lowest order instance starts with n. Implements the nodal basis of degree n the reference Tetrahedron cell. The basis has cardinality n(n+1)(n+3)/2 and spans an INCOMPLETE polynomial space of degree n. Basis functions are dual to a unisolvent set of degrees-of-freedom (DoF) defined and enumerated as follows:

If the pointType argument to the constructor specifies equispaced points, then the face and interior points will be equispaced. If the pointType argument specifies warp-blend points, the interior of a warp-blend lattice will be used on each face and also for the cell interior.

void Intrepid::Basis_HDIV_TET_In_FEM< Scalar, ArrayScalar >::getValues ( ArrayScalar &  outputValues,
const ArrayScalar &  inputPoints,
const EOperator  operatorType 
) const [virtual]

Evaluation of a FEM basis on a reference Tetrahedron cell.

Returns values of operatorType acting on FEM basis functions for a set of points in the reference Triangle cell. For rank and dimensions of I/O array arguments see Section MD array template arguments for basis methods .

Parameters:
outputValues[out] - variable rank array with the basis values
inputPoints[in] - rank-2 array (P,D) with the evaluation points
operatorType[in] - the operator acting on the basis functions

Implements Intrepid::Basis< Scalar, ArrayScalar >.
